My invention relates to coil handling apparatus, particularly but not exclusively to a device for receiving and upending coils of strip metal.

The invention will be best understood from the following description when read in the light of the accompanying drawings of an embodiment of the invention selected for .illustrative purposes, while the scope of the invention will be more particularly pointed out in the appended claims.

on an enlarged scale.

Referring to the drawings, which show a preferred form of the invention, the coil I of thin sheet metal, for example brass, is wound on the drum or so-called blocker 3 as the coil leaves the rolling mill or other apparatus which forms or treats it. The blocker 3, as indicated in Figs. 1, 2 and 3, is a sleeve of cylindrical exterior having a. polygonal bore 5 which permits it to be slipped over the rotating blocker shaft 1, having the same cross-section as that bore, and removed therefrom.

As is indicated by Fig. 1, the blocker 3 with the coil I thereon may be slipped from theblocker shaft 1 to place it on a cylindrical arbor 9 which rotatably receives it. As illustrated, this arbor is a prolongation of a piston rod for the piston II, which latter is reciprocally received within a cylinder I3. As shown, the front head I5 of s() the cylinder is formed with an elongated sleevelike projection I1 the outer end of which is flanged to form a table' I9 upon which the coil rests when the parts are in the position shown by Fig. 8.

u As shown, the front head I5 of the cylinder Application June 29, 193s, serial No. 216,515

I3 is formed with perforated ears 2l (see Fig. 9) receiving the projecting ends of trunnions 23 xedly carried by standards 25 at the outer sides of the cars. By this construction the part comprising the cylinder I3 and table I9 is mounted for swinging movement so that thatl part has a position illustrated by Fig. l in which it receives the coil and blocker 3 and a position illustrated by Fig. 8 in which the coil and blocker are turned on end. 10

In the present embodiment of the invention, for swinging the cylinder I3 and associated parts a cylinder 21 is provided in which is reciprocally mounted a piston 29. The piston rod 3| rigidly attached to the piston 29 is pivotally connected at 33 to an arm 35 formed integrally With the sleeve I1. As shown, the lower head 31 of the cylinder 21 is formed with a perforated ear 39 which is pivoted at 4I to a fixed bracket 113 so that the cylinder 21 may swing about the axis 20 of the pivot 4I when the piston 29 is reciprocated for swinging the cylinder I3 and associated parts on the trunnions 23.

For reciprocating the piston 29, in the present embodiment of the invention pressure iluid, pref- 25 erably compressed air, is admitted to and exhausted from opposite ends of the cylinder 21 by operator controlled means. This means in the present embodiment of the invention comprises an oscillatory plug valve 45 (Fig. '7), the casing I1 of which is mounted on the iioor in any convenient position so that it may be operated by foot treadles 49. As shown, compressed air is admitted to the bore 5l of the valve casing from a suitable connection 53 leading from a source of compressed air supply and communicating with a port 55 opening into the bore 5I. In the valve casing at opposite sides of the port 55 are ports 51 in communication with short lengths of pipe 59. To these pipes are attached ilexible o hoses 6I (Fig. 1) in communication with opposite ends, respectively, of the cylinder 21. A port 53 places the bore of tne valve casing in communication with the atmosphere, the valve 45 being provided with an exterior arcuate groove adapted to place this port in communication with either port 51 so that opposite ends of the cylinder- 21 may be alternately exhausted to the atmosphere. Similarly the valve is provided with an exterior arcuate groove 61 adapted to place either of the ports 51 in communication with the compressed air supply port 55 so-that either 'end of the cylinder 21 may be supplied with pressure fluid while the opposite end thereof is connected to the atmosphere.

As shown, the foot treadles 49 are pivoted at 69 to opposite sides, respectively, of the valve casing 41. The stem II of the valve xedly carries an arm 'I3 (Fig. 5), each end of which is connected by a bent up wire link 'I5 to the adjacent foot treadle. In the position of parts illustrated by Figs. l, 4, 6 and 7 the lower end of the cylinder 2l is connected to the atmosphere and compressed air is admitted to the upper end of the cylinder 2l to hold the piston 29 in its lowermost position. By pressing the uppermost foot treadle 49 of Figs. l and 4 down the valve 45 will be turned counter-clockwise to admit pressure uid to the lower end of the cylinder and exhaust its upper end, which will move the piston 29 to the upper end of its stroke and tilt the cylinder I3 and associated parts into the position illustrated by Fig. 8.

When the parts have been moved into the position shown by Fig. 8 the piston II is moved by operator controlled means, to the end of its stroke opposite that shown in Fig. 1, to withdraw the arbor 9 from the blocker 3. whereupon the operator by rotating the blocker back and forth may loosen it from the coil and remove it therefrom for replacement on the blocker shaft 1, and after removal of the blocker may push the coil sideways from the table I9 to place it on a truck, conveyer, or other suitable support il.

For controlling the reciprocation of the piston II, in the present embodiment of the invention there is secured to the sleeve I1 the casing 'I9 (Fig. 8) of a plug valve 8l (Figs. 9 and l0), which valve may be oscillated by a handle 83. As illustrated, communicating with the bore 85 for the valve 8| is a port 8l which may be supplied with motive uid, preferably compressed air, by means of a flexible hose (not shown) connected to a short length of pipe 89. A further port 9I in communication with this bore connects it to the atmosphere, while one port of a pair of ports 93 in communication with' the bore is connected by a pipe 95 to one end of the cylinder I3 and the other by a similar pipe 95 to its opposite end. By means of the arcuate grooves 97 and 99 formed on the exterior surface of the valve the two pipes 95 may be alternately placed in communication with the ports 8l' and 9|4 so as to admit motive iiuid to and exhaust it from the opposite ends of the cylinder I3 for reciprocating the piston II.

As illustrated, the table I9 is conveniently formed with a ring-shaped support IDI (see Fig. 12) for the end of the blocker 3 when the coil rests upon the table I9, this ring-shaped support being mounted on a ball thrust bearing |03 and being retained on the table I9 in any convenient way as, for example, by a ring IDS secured by screws I'I to the table.

It will be understood that within the scope of the appended claims Wide deviations may be made from the forms of the invention described without departing from the spirit of the invention.
